Specifically, inside heat pipe 10 located the cooking utensils, accessible screw or welding were fixed, heat pipe 10 was the annular structure that spirals to wholly be the back taper structure, heat pipe 10 adopts the stainless steel preparation. One end of the heat pipe 10 is connected to a water inlet pipe 11 and a water return pipe 12, and the other end is provided with a water outlet pipe 13, the water inlet pipe 11 is provided with an electromagnetic valve a111, and the water return pipe 12 is provided with an electromagnetic valve b121 and a water pump a 122. The water inlet pipe 11, the water return pipe 12 and the water outlet pipe 13 are all arranged below the stove to keep the cleanness of the stove table top.

Specifically, the relay water tank 20 is communicated with the water return pipe 12 and the water outlet pipe 13, and the relay water tank 20 is provided with a water temperature sensor 21 and a liquid level sensor a 22. The water temperature sensor 21 is located at the bottom of the relay water tank 20 for detecting the temperature of water in the relay water tank 20. The liquid level sensor a22 is installed at the middle height of the transfer water tank 20, and when the liquid level in the transfer water tank 20 is lower than the liquid level sensor a22, the heat conduction pipe 10 is filled with water through the water inlet pipe 11.
